How to automatically put quotes around contents of every cell, incl. blank cells?

I'm migrating data from Financisto for Android to CashTrails for iOS, and I need to format my CSV file a specific way for conversion to a CashTrails file.

I'd like to do the following in Excel 2013 (I have access to other versions if I need to):
1. Highlight a range of cells (i.e. A1-H20)
2. Apply following action: IF cell has data, add " to beginning of cell and " to end of cell, AND IF cell has no data, place "" in cell.

This can be done, right? I'm desperate!

It would look like this in Notepad.
Before:
Date,Time,Amount,Category,Tags,Account
12/31/13,12:00 PM,$3.99,General,,Checking
12/31/13,12:30 PM,$5.00,Shopping,gift,Cash

After:
"Date","Time","Amount","Category","Tags","Account"
"12/31/13","12:00 PM","$34.99","General","","Checking"
"12/31/13","12:30 PM","$5.00","Shopping","gift","Cash"

Thank you so much! Perfect!

Everything looked fine in Excel, but after saving and opening in Notepad, there were triple quotes. I just did a find and replace of """ with " and all is well
